IMPROVEMENT IN MECHANISMS FOR SHRINKING AND DRYING CLOTH.

Specification forming part of Letters Patent No. 155,108, datedSeptember 1 1874 application filed August 5, 1874.

To all whom it may concern:

Be it known that I, WILLIAM ROBERTSON, of Yorkville, in the county ofYork, in the Province of Ontario, Canada, have invented certain new anduseful Improvements on 010th Shrinking and Drying Machines; and I dohereby declare that the following is a full, clear, and exactdescription of the same.

This invention relates to a machine or apparatus for shrinking orsponging cloth by steam saturation, and drying the same by steam heat,the object being to steam and dry the cloth without removing it from theperforated cylinder on which it is to be wound; and it consists of aperforated cylinder having connected steam-inlet pipes and internalheating-pipes, and an adjustable gage telescoping on the end, to be usedin connection with a suitable steam generator and supportingframe.

The drawing represents a perspective view of my improved machine, theperforated cylinder being partly broken to show the internalheating-pipes.

A is a frame or stand, of any suitable construction, to receive theperforated cylinderB horizontally, which is supplied with steam from asteam generating apparatus, which may consist simply of a boiler, b, andlamp 6 underneath. G is a feed-pipe to convey steam from the generatorto the cylinder, and which cylinder contains a series or system ofpipes,

. D, of which E is the inlet, branching from the pipe I, and F theoutlet, provided with a suitable cock, G. The pipe 1 is provided with acock, H, and enters the cylinder centrally at the end, to dischargesteam directly into the cylinder, or connecting with or forming anintegral portion of a perforated pipe, J, running longitudinally throughthe cylinder to distribute steam therein, or connecting with a sleeve ofa tubular gage, J, coxering one end of the cylinder, and telescopingthereon to cover the perforations in the cylinder B not covered by thecloth. Thus the gage can be regulated to suit any width of cloth.

The cloth being wound around the cylinder, steam is admitted through theinlet I, and, when the cloth is sufficiently saturated, the valve H isclosed. The steam then passes through the inlet E into the pipes D,heating the same and drying the cloth. After the steam has passedthrough the pipes D it can escape through the outlet by opening thecock.

I claim as my invention- The perforated cylinder B, provided withsteam-inlets I E and outlet F, internal steam heating-pipes D, andadjustable gage J, for use in connection with a suitable steam-generatorfor shrinking and drying cloth, as set forth.

W. ROBERTSON.
